Known by various names/titles, "Ski Bergan", "H-Frame Bergan", "Arctic Bergan" among others!
I've still got mine, it's in the loft! Along with my "Cover, Sleeping Bag Arctic"
The frame on mine is a dark bronze green with a makers plate riveted to the frame, (Karrimor), cant remember the date though, will have to check later when it's daytime!:-)
IMO, a good piece of kit, decent amount of stowage space and lots of lashing points/loops, even if it is a bit heavy before it's loaded and virtually bomb-proof.
@Eaglehurst The Rucksack GS and Ruck SAS/Para used the same basic frame as the Clansman radio set and they were/are VERY heavy before they are loaded. The main difference between these these two are the actual pack size, big on the GS and huge in comparison on the SAS/Para version. Also, the SAS/Para very had tape ties for the lid whereas the GS version has straps and slider buckles.
Hope this is of some help
Regards etc
